Tire Pyrolysis Plant

Through thorough decomposition, the polymers in scrap tires can be cracked into smaller molecules or monomers. In this way, scrap tires are converted into high-value products such as pyrolysis oil, recovered carbon black, steel, and non-condensable combustible gas via the scrap tire pyrolysis process. By ensuring safety, environmental protection, and continuous, stable operation, the effective recycling of waste tires can be realized.

Technical Process

Niutech’s Intelligent Continuous Scrap Tire Pyrolysis Equipment has been honored with China’s top Environmental Protection Science and Technology award: the State Scientific and Technological Progress Award. This equipment is composed of seven advanced systems, including the intelligent feeding system, continuous pyrolysis system, NCG scrubbing system, oil separating and cooling system, circulating water cooling system, flue gas purification system, and intelligent discharging system. Equipped with the world’s leading fully automated control system, the equipment minimizes labor requirements by automating the entire production process.

Pyrolysis Process

While prioritizing safety and environmental protection, as well as economic efficiency and green, low-carbon operation, the equipment efficiently converts scrap tires into high-value products such as regenerated oil, pyrolytic carbon black, steel wire, and non-condensable gas. This process realizes the continuous disposal of large volumes of scrap tire pyrolysis, making it an effective and sustainable solution.

Sub System

Feeding ——The raw material is automatically transported to the transition hopper via the feeding conveyor. This system can also achieve functions such as online weighing, conveying, and feeding sealing.
Pyrolysis——In the oxygen-free or oxygen-poor environment, the pyrolysis system function is to complete the pyrolysis reaction of organic waste or hazardous waste and convert the raw material into pyro oil, NCG and solid output under normal pressure, low pyrolysis temperature or catalyst action.
NCG scrubbing——While removing acid components in NCG, such as hydrogen sulfide, the pressure is also maintained within a reasonable range through the NCG scrubbing system. This process further supplies energy to downstream operations.
Circulating water cooling——The main function of this system is to cool the outputs from pyrolysis system and flue gas with water as cooling medium. The cooling water is circulated in the way of in-direct heat exchange, which does not contact any material directly, and there’s no waste water generated.
Oil separating and cooling——This system is to cool the gas phase output from pyrolysis reactor to the safe temperature and separate them according to the different boiling points.
Discharging——The main function of discharging system is to complete the discharge seal, cool and convey the solid output.
Flue gas purification——The main function of this system is to cool down and purify the flue gas. Through multi-stage purification and comprehensive treatment, the harmful substances in the flue gas can be removed, and the flue gas discharged into the atmosphere can meet the emission standards in various countries and regions.
Electrical control——Electrical control system adapts PLC/DCS control system to automatically control the control points. It also has the functions of date collection, calculation, record, printing record, safety alarming etc.
